Abstract
A technique is provided for beamforming training, including: transmitting, by a network node, common control signaling via a plurality of beams periodically according to a predetermined beam sweeping pattern, and transmitting, via a set of one or more beams in each of one or more sequential time-domain resources, an aperiodic downlink sounding burst to at least one user device to allow the at least one user device to perform beamforming training.
Claims20
An apparatus comprising at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the apparatus to:
- transmit common control signaling via a plurality of beams periodically according to a predetermined beam sweeping pattern;
- and
- transmit, via a transmission beam in each of one or more sequential time-domain resources, an aperiodic downlink sounding burst to at least one user device to enable the at least one user device to perform beamforming training.
A method for beamforming training, comprising:
- receiving, by a user device from a network node, common control signaling via a plurality of beams periodically according to a predetermined beam sweeping pattern;
- receiving, via a transmission beam in each of a plurality of sequential time-domain resources, an aperiodic downlink sounding burst;
- and
- performing beamforming training of a set of one or more receiving beams based on the aperiodic downlink sounding burst to select a downlink receive beam for receiving signals from the network node.
